Who is choosing?

Vegan ingredient-checking shoppers

If you avoid intentionally used animal-derived ingredients, the ingredient list takes precedence over a lower-fat claim. Ambrosia Light and Tesco Reduced Fat ready-to-serve custards list milk ingredients; making custard from powder also means checking the preparation liquid.

Convenience-first dessert shoppers

If you want custard ready to heat or pour and do not require it to be vegan, a ready-to-serve format may suit you. Ambrosia's and Tesco's fat-reduction claims compare specific products with their own standard custards; they do not establish vegan suitability.

Shoppers preparing their own custard

If you are willing to make custard, you can choose the plant milk, added sugar and serving size. Check the powder separately: Sainsbury's No Added Sugar Instant Custard Powder, for example, lists whey powder and cows' milk protein.

What matters when buying?

For a lower-fat custard purchase connected to vegan shopping, decide whether vegan ingredients, ready-to-serve convenience or control over the prepared recipe is your primary concern. A dairy ready-to-serve product fits only if vegan suitability is not required.

Concern What to check Who this matters to
Vegan ingredients Read the current ingredients for milk, buttermilk, whey and milk proteins. Check precautionary allergen wording separately if milk allergy is relevant. When I need to avoid intentionally used animal-derived ingredients, a lower-fat claim cannot settle whether the custard belongs on my shopping list. About 50% of consumers would put vegan ingredient suitability first.
Ready-to-serve convenience Confirm that the product is ready to serve rather than a powder, and check its ingredients before relying on “light” or “reduced fat”. If I need custard I can heat or pour without making it, I may accept a dairy product instead of a vegan one. Ready-to-serve convenience would be the primary concern for about 30% of consumers.
Recipe control Check whether nutrition is given for the powder or for custard prepared with a specified milk; use your chosen plant milk and added sugar when assessing the finished recipe. Making custard lets me choose the preparation liquid and how much sugar to add, rather than relying on figures for a different recipe. About 20% of consumers would prioritise control over the finished custard.

Label checks to avoid mistakes

  • Assuming “light” means vegan

    Ambrosia Light and Tesco Reduced Fat ready-to-serve custards list milk-derived ingredients. A fat-reduction claim does not change that ingredient check.

    When vegan suitability is required, check the current label for milk, buttermilk, whey and milk proteins before choosing a product.

  • Treating vegetarian labelling as a vegan claim

    A vegetarian description does not establish that a custard or its finished recipe avoids animal-derived ingredients.

    Read the full ingredient list and, if using powder, check what you will mix it with.

  • Using a vegan label instead of allergen information

    GOV.UK guidance explains that a vegan label does not guarantee the absence of animal-origin material through cross-contact. The Food Standards Agency likewise cautions people with food hypersensitivities against using vegan labelling as a substitute for allergen checks.

    If milk allergy is relevant, read the allergen and precautionary statements rather than relying on a vegan description alone.

  • Applying dairy-prepared nutrition to a plant-milk recipe

    Bird's published prepared nutrition uses semi-skimmed milk, so those figures do not describe custard made with a different liquid.

    Assess the finished custard using the plant milk, added sugar and serving size you will actually use.

Relevant brands for reference

Ambrosia

Its Ready To Serve Light Devon Custard is a 400g tin for shoppers who want prepared custard and do not require a vegan product.

  • Ambrosia states that this tin has 30% less fat and 30% less sugar than Ambrosia Devon Custard.
  • It lists skimmed milk, buttermilk and whey, so it does not fit vegan shopping.

Bird's

Original Custard Powder is a make-at-home alternative to ready-to-serve tins.

  • Bird's says the powder thickens with soya and rice milk; its listed ingredients do not include milk or egg.
  • The pack says “May contain: Milk”, and preparation is required. Nutrition for custard prepared with semi-skimmed milk does not describe a plant-milk recipe.

Tesco

Tesco Reduced Fat Custard is a ready-to-serve option for shoppers who accept dairy ingredients.

  • Tesco states that it contains 40% less fat than standard Tesco Ready To Serve Custard.
  • It lists dried skimmed milk, buttermilk powder and milk proteins, so it is not a vegan option.

Sainsbury's

Its No Added Sugar Instant Custard Powder is prepared with boiling water, rather than supplied as ready-to-serve custard.

  • The no-added-sugar description addresses a different label claim from vegan suitability.
  • This powder lists whey powder and cows' milk protein, despite its water-only preparation method.

M&S

Silky Smooth Custard is a ready-to-serve tinned product made with whole milk.

  • Its ingredients include whole milk, skimmed milk, cream and whey powder, so it does not meet the vegan-shopping requirement.

Bird's Custard Powder 350g

Bird's Custard Powder 350g

This 350g powder suits shoppers willing to prepare custard with a chosen plant milk instead of buying it ready to serve.

Common questions

Is lower-fat tinned custard vegan?

A lower-fat claim does not establish vegan suitability. Ambrosia Ready To Serve Light Devon Custard lists skimmed milk, buttermilk and whey, while Tesco Reduced Fat Custard lists milk-derived ingredients. Check the current ingredient label of any tin you are considering.

Can I make Bird's Original Custard Powder with plant milk?

Yes. Bird's says its Original Custard Powder thickens with alternatives including soya and rice milk, although the finished flavour changes. Its listed ingredients do not include milk, but the pack carries a “May contain: Milk” statement.

Does a vegan label settle a milk-allergy check?

No. GOV.UK guidance says vegan labelling does not guarantee the absence of animal-origin material through cross-contact. Read allergen and precautionary information separately when milk allergy is relevant.

Does “no added sugar” mean custard is vegan or lower in fat?

No: those are separate product characteristics. Sainsbury's No Added Sugar Instant Custard Powder lists whey powder and cows' milk protein. Check ingredients for vegan suitability and the nutrition information for the product and preparation method you intend to use.
